Not algae, but some sort of fuzzy, light tan, photosynthetic, (and I assume) bacteria. It grows mostly on the plastic surfaces inside the tank, and to a lesser extent the rocks. It can be blown or brushed all of all the surfaces easily, but returns in less than 24 hours. I just can't get it to go away.
I've tried waiting it out, then tried Vibrant, Chemiclean, lights out, water changes, no water changes, skimming wet, no skimming, raising nitrates, lower nitrates, & etc.. Nothing seems to have any long term effect.
Right now N reads about 10ppm, P is about .07ppm... pH stays 7.9-8.1... Temp stays 80+/-1 F... Salinity is 34ppt. I have a 8X 54 W Sunpower that ramps up to 50% over a 4 hour period, holds for 3 hours, and then ramps down for 4 hours. It has 6X Blue Plus and 2X Purple Plus bulbs. I currently have a skimmer and a small GAC reactor running. I started the tank with dry rock and a few piecs of live rock about 8 months ago, and except for some red turf algae (or sponge) I don't have algae issues.
The tank is a 90 gallon and the rocks are glued/cemented together so removal is not an option. There are no corals in the tank yet. I'm contemplating trying peroxide, but am kind of worried about putting it in the tank.
Does anyone have any suggestion that might help me rid my tank of this pest? Thanks.
